This module provides a means to edit an order item's attributes after the order has been placed. Typical use case is someone ordered the wrong size, or dinner, or something.

It is built for Ubercart's Attributes. Users with "edit orders" permission may go to the order edit page. On the far right, each order item's attributes are listed, along with an "edit" link which will take the user to an edit page. Enter the new values there and submit.
